Despite the high level of acoustic control and technology that is prevalent among modern commercial, business, and defense aircraft for achieving general comfort, the internal spaces of many vessels can still be loud at times as a result of vibration and reverberating forces that stem from engine operations, atmospheric drag, and beyond. While this level of noise may not be enough to cause actual discomfort or concern, it can detract from the ability of pilots and crew members to be able to effectively communicate with one another or ground personnel. As such, it is common for advanced headsets with reliable ear covers to be used within cockpits, ensuring that any spoken word can be relayed and received with full clarity, where external noises do not compete or deter communication. In this blog, we will provide an overview of the various headsets and cover parts that currently support pilots in operations across the globe, so read on if you are interested in learning more.
What Are Aviation Headset Cover Parts?
Headset covers encompass a variety of textile and composite materials that are specifically designed to create an airtight or reliable seal around a wearer’s ear while providing a secondary layer of acoustic filtration. These components tend to work in tandem with active and passive noise reduction systems to further isolate a user from the high-decibel frequency ranges commonly encountered in the cockpit during flight, promoting ease of communication.
Most aviation headset cover parts are replaceable components, being found around ear cushions and microphone areas, as well as on headbands and storage-facing surfaces. Unlike the electronics they surround and augment, cover parts do not influence signal processing or transmission. As such, their role is purely physical in preserving the surfaces most exposed to handling and environmental wear while also ensuring sound clarity by muting competing noises.
Notable Aviation Headset Cover Parts
-
Ear Cushion Covers: Cushion covers are placed over or around the ear cushion area of a headset, proving essential in preserving its Passive Noise Reduction (PNR) rating. The quality of any chosen leatherette or material is crucial, as poor-quality options that degrade quickly will face air gaps that reduce passive attenuation.
-
Microphone Foam Covers: Foam covers are often fitted over the microphone element of a headset, improving the quality of speech while shielding electronics from any moisture or debris.
-
Headband Covers: These covers sit along the area that rests against the user’s head, helping preserve the surface and provide a cleaner and more comfortable contact point during extended durations of wear.
-
Storage or Protective Covers: Many headsets will come with shielding covers or storage solutions that safeguard equipment when they are not in use, with flight bags, compartments, and other cockpit organization tools commonly being leveraged for such needs.
Tips for Securing Fitting Aviation Headset Cover Parts
When it comes to selecting an appropriate replacement cover for any headset, professionals need to take the time to analyze options based on their compatibility with the specific mechanical interface of equipment or environmental stressors of concern. This is to ensure that chosen options avoid compromising the integrity of a headset’s acoustic seal, which is paramount for basic noise cancellation or control. As such, any procurement endeavor should include:
-
Model-Specific Cross-Referencing: While one may begin with a manufacturer part number for a search, utilizing National Stock Number (NSN) data that is associated with items of need can ensure ease of confirming compatibility and the alignment of technical specifications.
-
Material Durability Assessment: It can often be useful to take advantage of headsets with medical-grade silicone or high-density foam covers that better resist degradation from UV exposure, hydraulic fluid intrusion, and frequent sterilization.
-
TSO Compliance Verification: Always be sure that any chosen replacement parts meet Technical Standard Order (TSO) requirements for fire retardancy and environmental resilience in aerospace applications, as well as any other industry specifications of concern.
-
Vendor Traceability: Only source desired components through authorized distributors or entities that can provide Certificates of Conformance (CoC) and full traceability records to guarantee the authenticity and performance of the noise-reduction materials.
